Although the key assembly 120 has a plurality of arrangements, the first to fifth key arrays 121, 122, 123, 124, and 125 are provided in FIG. 4, but only four key arrays may be provided as necessary. 3 and 4 illustrate that the first key array 121 is a touch type. The first key array 121 may be a touch type, but the present invention is not limited thereto, and the fifth key array 125 is not limited thereto. You can also touch.
또한, 도 2a, 도 2b 및 도 5를 참조하면, 상기 연결부(135)는 인쇄회로 패턴(173)이 형성되어 있는 패턴시트(170)와, 상기 패턴시트(170)의 상부 및 하부에 배치되어, 상기 패턴시트(170)를 보호하는 프론트 시트(front sheet,160)와 리어 시트(rear sheet,180)를 포함하여 이루어진다. 본 발명의 일 실시예에 따른 연결부(135)는 상기 프론트 시트(160), 패턴 시트(170) 및 리어 시트(180)를 포함하여 이루어지는데, 이들 시트는 얇은 재질로 되어 있어, 키조립체(120) 중 첫 번째 열에 있는 제1 키배열(121)이 쉽게 권취될 수 있도록 한다. 이때, 상기 연결부(135)는 상기 기계식 키배열(122,123,124,125)의 하부에까지 확장되어 있다.2A, 2B, and 5, the connection part 135 is disposed on the pattern sheet 170 on which the printed circuit pattern 173 is formed, and on the upper and lower portions of the pattern sheet 170. A front sheet 160 and a rear sheet 180 that protect the pattern sheet 170 are formed. Connection portion 135 according to an embodiment of the present invention comprises the front sheet 160, the pattern sheet 170 and the rear sheet 180, these sheets are made of a thin material, the key assembly 120 The first key array 121 in the first column of) can be easily wound up. At this time, the connecting portion 135 is extended to the lower portion of the mechanical key array (122, 123, 124, 125).
도 2a는 제1 키배열(121)이 터치식이고 나머지 키배열(122,123,124,125)이 기계식인 것을 도시한 것이다. 도 2b는 기계식 키배열이 권취되는 모습을 도시한 것인데, 도 2b에 도시된 바와 같이, 상기 연결부(135)는 굴곡되는 부분(191)이 발생하므로, 이와 같이 휘어지도록 하기 위해서 본 발명의 일 실시예에서는 프론트 시트(160) 및 리어 시트(180)를 PU(Polyurethane) 재질을 사용하였고, 패턴 시트(170)는 PET 필름을 사용하였다.FIG. 2A illustrates that the first key array 121 is a touch type and the remaining key arrays 122, 123, 124, and 125 are mechanical. Figure 2b is a mechanical key array is shown to be wound, as shown in Figure 2b, the connecting portion 135 is a curved portion 191 is generated, so as to be bent in one embodiment of the present invention In the example, the front sheet 160 and the rear sheet 180 were made of PU (Polyurethane), and the pattern sheet 170 was made of PET film.
이때, 키(126)의 상면(126c) 중 일부 영역(126b)에는 문자 또는 숫자 등이 인쇄되어 있고, 상면(126c)은 상기 몸체(110)의 일면과 접촉하고, 키(126)의 측면(126d)은 인접한 키(126)의 측면(126d)과 이격되어 있으며, 상기 키 받침부(140)의 측면(140a)은 경사져 있는데, 인접한 측면(140a)끼리 접촉하지 않도록 하기 위하여 권취되었을 때에 평행하게 배치되도록 형성할 수도 있고, 측면(140a)끼리 접촉하도라도 그 접촉에 의해 인접 형성되는 두 개의 키 받침부(140)가 직각을 형성하도록 한다. 이때, 상기 키(126)의 측면(126d)과 측면(126d) 또한 접촉되지 않도록 배치되어야 한다.In this case, letters or numbers are printed on some areas 126b of the upper surface 126c of the key 126, and the upper surface 126c is in contact with one surface of the body 110, and the side surface of the key 126 ( 126d is spaced apart from the side 126d of the adjacent key 126, and the side 140a of the key support 140 is inclined, in parallel when wound to prevent the adjacent side 140a from contacting each other. It may be formed so as to be arranged, even if the side (140a) is in contact with each other so that the two key support portion 140 formed adjacent by the contact to form a right angle. At this time, the side 126d and the side 126d of the key 126 should also be arranged so as not to contact.
이때, 상기 키(126)는 상기 키 받침부(140)의 상면(140b)에 접촉될 수 있는데, 상기 키(126)의 폭(D1)은 상면(140b)의 폭(D2)보다 좁으며, 상기 측면(140a)이 경사져 있기 때문에 상기 상면(140b)의 폭(D2)은 키 받침부(140)의 전체 폭(D3)보다 좁게 되어 있다.In this case, the key 126 may be in contact with the upper surface 140b of the key support 140, the width (D1) of the key 126 is narrower than the width (D2) of the upper surface (140b), Since the side surface 140a is inclined, the width D2 of the upper surface 140b is narrower than the overall width D3 of the key receiving portion 140.
한편, 상기 몸체(110)의 폭(L)은 상기 키배열(121,122,123,124,125)의 키 받침부(140)의 폭(D3)과 관련되는데, 만약 폭(L)이 커진다면, 이에 따라 키 받침부(140)의 폭(D3) 또한 커져야 하므로, 몸체(110)를 과도하게 형성하면 키조립체(120)의 형성이 곤란해질 수 있다. 만약, 몸체(110)의 크기를 크게 하고자 한다면, 상기 키배열(121,122,123,124,125) 간의 간격을 보다 넓게 형성해야 할 것이다.Meanwhile, the width L of the body 110 is related to the width D3 of the key support portion 140 of the key arrays 121, 122, 123, 124, and 125. Since the width D3 of the 140 must also be large, excessively forming the body 110 may make it difficult to form the key assembly 120. If the size of the body 110 is to be increased, the spacing between the key arrays 121, 122, 123, 124, and 125 will be wider.
또한, 상기 키(126)는 외부로 이탈되는 것을 방지하기 위하여, 하단부가 횡으로 뻗어 있는 이탈 방지부(126a)가 형성되어 있다. 상기 이탈 방지부(126a)는 키 받침부(140)에 형성된 관통홀(140c)을 지나면서 돔(150)과 접촉하는 부분이 관통홀(140c)보다 큰 직경을 갖도록 형성된다.In addition, in order to prevent the key 126 from escaping to the outside, an anti-separation part 126a having a lower end extending laterally is formed. The detachment preventing part 126a is formed such that a portion contacting the dome 150 has a larger diameter than the through hole 140c while passing through the through hole 140c formed in the key receiving part 140.

상기에서는 제1 요소(119) 및 제2 요소(130)의 자력에 의한 결합에 의해 용이하게 권취할 수 있는 것을 설명하였으나, 이러한 자력을 이용한 방법 외에도 다양한 방법이 가능하다. 예를 들면, 도 13에 도시된 바와 같이, 몸체(110)의 각 면에는 홈(161)이 형성되고, 키조립체(120)의 각각의 키배열(121,122,123,124,125)의 끝단에는 상기 홈(161)과 대응되는 돌기(162)가 형성되어 요철 결합에 의해 용이하게 권취될 수도 있다. 이에 대하여는 후술하기로 한다.In the above description, the first element 119 and the second element 130 have been described to be easily wound by the coupling by the magnetic force.

이 중, 휴대용 키보드(100)에 구비된 NFC 모듈은 10cm 안팎의 거리에서 단말 간 비접촉식 근거리 무선 통신을 지원한다. NFC 모듈은 카드 모드, 리더 모드 및 P2P 모드 중 어느 하나로 동작할 수 있다. NFC 모듈이 카드 모드로 운용되기 위해서, 휴대용 키보드(100)는 카드 정보를 저장하는 보안 모듈을 더 포함할 수도 있다. 여기서, 보안 모듈이란 UICC(Universal Integrated Circuit Card)(예컨대, SIM(Subscriber Identification Module) 또는 USIM(Universal SIM)), Secure micro SD 및 스티커 등 물리적 매체일 수도 있고, 이동 단말기에 임베디드되어 있는 논리적 매체(예컨대, embeded SE(Secure element))일 수도 있다. NFC 모듈과 보안 모듈 사이에는 SWP(Single Wire Protocol)에 기반한 데이터 교환이 이루어질 수 있다.Among these, the NFC module provided in the portable keyboard 100 supports contactless short-range wireless communication between terminals at a distance of about 10 cm. The NFC module may operate in any one of a card mode, a reader mode, and a P2P mode. In order for the NFC module to operate in a card mode, the portable keyboard 100 may further include a security module that stores card information. Here, the security module may be a physical medium such as a universal integrated circuit card (UICC) (for example, a subscriber identification module (SIM) or a universal SIM (USIM)), a secure micro SD, and a sticker, or a logical medium embedded in a mobile terminal ( For example, it may be an embedded SE (Secure Element). Data exchange based on a single wire protocol (SWP) may be performed between the NFC module and the security module.
NFC 모듈이 카드 모드로 운용되는 경우, 휴대용 키보드(100)는 전통적인 IC 카드처럼 저장하고 있는 카드 정보를 외부로 전달할 수 있다. When the NFC module is operated in a card mode, the portable keyboard 100 may transmit card information stored like a conventional IC card to the outside.
NFC 모듈이 리더 모드로 운용되는 경우, 휴대용 키보드(100)는 외부의 태그(Tag)로부터 데이터를 독출할 수 있다. 이때, 이동 단말기가 태그로부터 수신하는 데이터는 NFC 포럼에서 정하는 데이터 교환 포맷(NFC Data Exchange Format)으로 코딩될 수 있다. 아울러, NFC 포럼에서는 4개의 레코드 타입을 규정한다. 구체적으로, NFC 포럼에서는 스마트 포스터(Smart Poster), 텍스트(Text), URI(Uniform Resource Identifier) 및 일반 제어(General Control) 등 4개의 RTD(Record Type Definition)를 규정한다. 태그로부터 수신한 데이터가 스마트 포스터 타입인 경우, 제어부는 브라우저(예컨대, 인터넷 브라우저)를 실행하고, 태그로부터 수신한 데이터가 텍스트 타입인 경우, 제어부는 텍스트 뷰어를 실행할 수 있다. 태그로부터 수신한 데이터가 URI 타입인 경우, 제어부는 브라우저를 실행하거나 전화를 걸고, 태그로부터 수신한 데이터가 일반 제어 타입인 경우, 제어 내용에 따라 적절한 동작을 실행할 수 있다.When the NFC module is operated in the reader mode, the portable keyboard 100 may read data from an external tag. In this case, the data received by the mobile terminal from the tag may be coded in a data exchange format (NFC Data Exchange Format) determined by the NFC forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four record type definitions (RTDs) such as smart poster, text, uniform resource identifier (URI), and general control. If the data received from the tag is a smart poster type, the controller may execute a browser (eg, an Internet browser). If the data received from the tag is a text type, the controller may execute a text viewer. When the data received from the tag is a URI type, the controller executes a browser or makes a phone call, and when the data received from the tag is a general control type, the controller can execute an appropriate operation according to the control content.
NFC 모듈이 P2P 모드로 운용되는 경우, 휴대용 키보드(100)는 다른 이동 단말기와 P2P 통신을 수행할 수 있다. 이때, P2P 통신에는 LLCP(Logical Link Control Protocol) 가 적용될 수 있다. P2P 통신을 위해 휴대용 키보드(100)와 다른 이동 단말기 사이에는 커넥션(connection)이 생성될 수 있다. 이때, 생성되는 커넥션은 1개의 패킷을 교환하고 종료되는 비접속형 모드(connectionless mode)와 연속적으로 패킷을 교환하는 접속형 지향 모드(connection-oriented mode)로 구분될 수 있다. P2P 통신을 통해, 전자적 형태의 명함, 연락처 정보, 디지털 사진, URL 등의 데이터 및 블루투스, Wi-Fi 연결을 위한 셋업 파라미터 등이 교환될 수 있다. 다만, NFC 통신의 가용 거리는 짧으므로, P2P 모드는 크기가 작은 데이터를 교환하는 것에 효과적으로 활용될 수 있을 것이다.When the NFC module is operated in the P2P mode, the portable keyboard 100 may perform P2P communication with another mobile terminal. In this case, LLCP (Logical Link Control Protocol) may be applied to P2P communication. A connection may be created between the portable keyboard 100 and another mobile terminal for P2P communication. In this case, the generated connection may be classified into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are continuously exchanged. Through P2P communication, data such as electronic business cards, contact information, digital photos, URLs, and setup parameters for Bluetooth and Wi-Fi connections can be exchanged. However, since the available distance of NFC communication is short, the P2P mode may be effectively used for exchanging small data.

전원 공급부(270)는 제어부(290)의 제어에 의해 내장 배터리(101)의 전원 및 이동 단말기 등의 외부 배터리(271)의 전원을 공급할 수 있다. 즉, 전원 공급부(270)는 내장 배터리(101)를 포함하며, 배터리는 충전 가능하도록 이루어지는 내장형 배터리가 될 수 있으며, 충전 등을 위하여 단말기 바디에 착탈 가능하게 결합될 수 있다. 이때, 내부의 전원을 인가 받아 각 구성요소들의 동작에 필요한 전원을 공급한다. The power supply unit 270 may supply power of the internal battery 101 and power of an external battery 271 such as a mobile terminal under the control of the controller 290. That is, the power supply unit 270 includes a built-in battery 101, the battery may be a built-in battery that can be charged, it may be detachably coupled to the terminal body for charging. At this time, the internal power is supplied to supply power for the operation of each component.
또한, 전원 공급부(270)는 승압을 위한 충전 구동칩(104)(IC chip)과, 내장 배터리(101)의 충전을 위한 충전포트(112) 및 이동 단말기(200)에 내장되어 있는 외부 배터리(271)를 충전하기 위한 USB 포트(108) 등이 포함될 수 있다.In addition, the power supply unit 270 is a charge driving chip 104 (IC chip) for boosting, the charging port 112 for charging the internal battery 101 and the external battery built in the mobile terminal 200 ( USB port 108 for charging 271 may be included.
도 18a 및 도 18b는 본 발명의 일 실시예와 관련된 내장 배터리 및 외부 배터리의 충전을 설명하기 위한 도면이다. 외부에서 공급되는 전압과 휴대용 키보드에서 사용하는 전압이 상이한 경우가 많은데, 이런 경우에는 전압을 승압 또는 강하시켜줘야 한다. 도 18a를 참조하면, 외부에서 5V 전원이 케이블(107)을 통해 충전포트(112)로 입력되면, 내장 배터리(101)에 맞는 전압으로 변환시켜줘야 한다. 이를 위하여 인쇄회로기판(103)에는 충전 IC칩(104)에 형성되어 있어, 전압이 변환된다. 즉, 상기 충전 IC칩(104)에 의해 5V의 전압이 3.7V로 강하된다. 이때, 상기 충전 IC칩(104)은 DC/DC 컨버터와 같은 기능을 수행한다.18A and 18B are diagrams for describing charging of an internal battery and an external battery according to an embodiment of the present invention. In many cases, the voltage supplied from an external device and the voltage used by a portable keyboard are different. In this case, the voltage must be boosted or lowered. Referring to FIG. 18A, when 5V power is externally input to the charging port 112 through the cable 107, it should be converted into a voltage suitable for the internal battery 101. To this end, the printed circuit board 103 is formed on the charger IC chip 104, and the voltage is converted. In other words, the voltage of 5V drops to 3.7V by the charger IC chip 104. In this case, the charger IC 104 performs the same function as the DC / DC converter.
이때, 충전포트(112)를 통해 외부의 전원이 인가될 수 있으며, 상기 충전포트(112)는 배터리의 충전을 위하여 전원을 공급하는 외부 전원이 전기적으로 연결되는 인터페이스의 일 예로서 구성될 수 있다.In this case, external power may be applied through the charging port 112, and the charging port 112 may be configured as an example of an interface to which an external power supply for supplying power for charging the battery is electrically connected. .
다른 예로서, 전원 공급부(270)는 상기 연결포트를 이용하지 않고 무선방식으로 배터리를 충전하도록 이루어질 수 있다. 이 경우에, 전원 공급부(270)는 외부의 무선 전력 전송장치로부터 자기 유도 현상에 기초한 유도 결합(Inductive Coupling) 방식이나 전자기적 공진 현상에 기초한 공진 결합(Magnetic Resonance Coupling) 방식 중 하나 이상을 이용하여 전력을 전달받을 수 있다.As another example, the power supply unit 270 may be configured to charge the battery in a wireless manner without using the connection port. In this case, the power supply unit 270 uses one or more of an inductive coupling based on a magnetic induction phenomenon or a magnetic resonance coupling based on an electromagnetic resonance phenomenon from an external wireless power transmitter. Power can be delivered.
한편, 이동 단말기의 외부 배터리(271)를 충전하기 위해서는 이동 단말기(200)와 휴대용 키보드(100)가 USB 포트(108)를 통하여 전기적으로 연결되어야 하는데, 이때도 역시 전압 조정이 필요하다.Meanwhile, in order to charge the external battery 271 of the mobile terminal, the mobile terminal 200 and the portable keyboard 100 must be electrically connected through the USB port 108. In this case, voltage adjustment is also required.
즉, 도 18b를 참조하면, 내장 배터리(101)로부터 케이블(102)에 의해 전원을 공급받는데, 내장 배터리(101)의 전압은 약 3.7V인데, 외부 배터리(271)를 충전하기 위해서는 약 5V의 전압으로 승압해야 하는데, 이는 충전 IC칩(104)에 의해 이루어진다. 상기 충전 IC칩(104)에 의해 승압된 전압은 케이블(106)을 통해 외부 배터리(271)에 충전된다. 이를 위하여, 본 발명의 일 실시예에서는 몸체(110)의 일 면에 USB 포트(108)를 구비하고 있다. 즉, 상기 케이블(106)은 USB 포트(108)에 연결되어 있다. 결국, 상기 내장 배터리(101)를 충전하는 경우에는 전압 강하가 필요하고, 외부 배터리(271)를 충전하는 경우에는 승압이 필요한데, 이들 변환은 충전 IC칩(104)에 의해 이루어지며, 상기 전압 강하와 승압의 과정은 서로 반대의 과정이다.That is, referring to FIG. 18B, power is supplied from the built-in battery 101 by the cable 102. The voltage of the built-in battery 101 is about 3.7 V. In order to charge the external battery 271, the The voltage must be boosted by the charging IC chip 104. The voltage boosted by the charger IC chip 104 is charged to the external battery 271 through the cable 106. To this end, in one embodiment of the present invention is provided with a USB port 108 on one surface of the body (110). That is, the cable 106 is connected to the USB port 108. As a result, when the internal battery 101 is charged, a voltage drop is required, and when the external battery 271 is charged, a voltage boost is required. These conversions are performed by the charger IC chip 104, and the voltage drop is performed. The process of and boosting is the opposite process.
